ScalaTest is a free, open-source testing toolkit for Scala and Java programmers.
Official Website: http://www.scalatest.org/
Please visit Download and Setup for download and setup instructions.
Please visit Quick Start for steps to get started quickly.
The followings are needed for building ScalaTest:
- JDK 6, 7 or 8
- [SBT 0.13.7] (http://www.scala-sbt.org/0.13/tutorial/Setup.html)
for JDK 6 or 7, use the following options in your SBT launch file:
SBT_OPTS="-server -Xms512M -Xmx3000M -XX:MaxPermSize=512M -Xss1m -XX:+CMSClassUnloadingEnabled -XX:+UseCompressedOops -XX:NewRatio=9 -XX:ReservedCodeCacheSize=100m"
for JDK 8, use the following SBT options instead:
SBT_OPTS="-server -Xms512M -Xmx3G -Xss1m -XX:+CMSClassUnloadingEnabled -XX:+UseCompressedOops -XX:NewRatio=9 -XX:ReservedCodeCacheSize=100m"
Building and Running Tests
This command will build and run the regular tests:
$ sbt test
To run generated tests, you'll need to increase maximum heap size to -Xmx5000M, and use this command instead:
$ sbt gentests/test
What it does is simply switch to gentests project and run test.
You can package the ScalaTest JAR file using this command:
$ sbt package
The resulting JAR file will be produced in target/scala-2.10/.
You can also publish it to your local Ivy repository using this command:
$ sbt publishLocal
Or publish it to a local maven repository using this command:
$ sbt publishM2
To publish to Sonatype, you first need to make sure you have the following:
- A GPG client is installed on your command line path. For more information, please refer to GNU Privacy Guard Website.
- You have created your GPG keys and distributed your public key to hkp://pool.sks-keyservers.net/. For more information, please refer to How To Generate PGP Signatures With Maven.
- You have been granted the right to publish using org.scalatest and org.scalactic domain.
By default, ScalaTest build will read your Sonatype credentials from ~/.ivy2/.credentials, which is a properties file that looks like this:
realm=Sonatype Nexus Repository Manager host=oss.sonatype.org user=xxxxxxxx password=xxxxxxxx
You can use SCALATEST_NEXUS_LOGIN and SCALATEST_NEXUS_PASSWORD environment variables to override Sonatype credentials.
For signing, ScalaTest build will use ~/.gnupg/secring.gpg by default and prompt for GPG passphase if required. Alternatively you can use SCALATEST_GPG_FILE to use a different GPG file, and use SCALATEST_GPG_PASSPHASE to provide GPG passphase to avoid input prompt.
If you would like to export a particular private key into a separate GPG file, you can use the following command:
$ gpg --export-secret-keys firstname.lastname@example.org > example-secret-key.gpg
With Sonatype credentials and GPG file in place, you can now publish to Sonatype.
To publish ScalaTest, use the following command:
$ sbt publishSigned
To publish Scalactic, use the following command:
$ sbt scalactic/publishSigned
